Hi everyone!My design has a power supply of 1.8V and i want a current source/sink to provide me from -10uA to 10uA but i don't have much experience in electronics and i don't have a clue ...Can anyone help me??
Thank you for your time.

My design has an ASIC with a pad in which i must provide the current i mentioned.I have a regulator,which gives me 1.8V(power supply to the ASIC) and through that pad i told you,current will be drawn or injected,depending on some other parameters (the ASIC internally has a circuit to absorve or provide current to some amplifiers but i don't know further details about it),so i have to provide current from -10uA to 10uA.Does this make any sense now or did i make it worse?
